Session 7 - A Comparative Geographic Analysis Of The Impact Of Scale On Hazards And Vulnerability In Industrialized Continental Lands And Small Pacific Islands, William J. Smith Jr.

International Symposium on Technology and Society

Geography, specifically scale, has significant impacts in terms of hazards and vulnerability. Small islands, such as those found in the Pacific, experience the impacts of their relatively unique geography and scale in terms of hazards and vulnerability in at least five ways: 1) Perception and communication; 2) Impact and escape from impact; 3) Technology; 4) Recovery; and 5) Socio-environmental justice. Comparative analysis in these five areas between the Pacific’s small islands and industrialized continental regions illuminates differences regarding the way hazards and vulnerability should be conceptualized in the under-treated small islands of the world. Lessons from this analysis will aid …

Session 6 - The National Environmental Policy Act (Nepa): Is It All That It Can Be? The Case For Evaluating Stigma Effects, Dennis Bechtel

International Symposium on Technology and Society

The National Environmental Policy Act (NEPA) has long been regarded as the“Magna Carta” of environmental policy legislation. The government in implementing its requirements on NEPA is required to evaluate potential environmental impacts from “significant” projects, to examine alternatives to proposed actions, and to enable the public to provide meaningful input to decision-makers. Despite the significance of NEPA there is evidence to suggest that environmental impact analyses may in fact be understating potential negative effects to citizens and communities. In particular potential impacts associated with stigma have been almost universally ignored in documents prepared under NEPA. The proposed high-level nuclear waste …

Extensions Of Local Domains With Trivial Generic Fiber, William Heinzer, Christel Rotthaus, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We consider injective local maps from a local domain R to a local domain S such that the generic fiber of the inclusion map R -> S is trivial, that is P R (0) for every nonzero prime ideal P of S. We present several examples of injective local maps involving power series that have or fail to have this property. For an extension R -> S having this property, we give some results on the dimension of S; in some cases we show dim S = 2 and in some cases dim S = 1.

Dynamics Of A Eutrophic Lake (Wilgreen Lake, Madison County, Kentucky): A First Step In Cleansing A Lake System Impaired By Nutrient Loading, Erin C. Jolly, Walter S. Borowski

EKU Faculty and Staff Scholarship

Wilgreen Lake (Madison County, Kentucky) is a eutrophic lake formed by damming Taylor Fork, part of the Silver Creek watershed. The lake is listed “nutrient impaired” by the Commonwealth and the EPA, and it is likely that nutrient input from human activities is affecting water quality. Our study aims first to characterize the physical characteristics and water quality of the lake (2006), and then to determine the specific proportion of nutrient inputs (2007) to the lake with the ultimate aim of improving its water quality.

Research started in May 2006 with work occurring throughout the 2006 field season with the …

Polar Research: School Of Rock, Alexandra Witze

ANDRILL Research and Publications

As Antarctica’s ice teams continue to hunt for the oldest ice their drills will reach, a smaller band of rockhounds is on a similar quest to plug the gaps in the geological record. The team now has a core that promises fresh insight into how Antarctica’s ice waxed and waned over the past few million years. On December 26, 2006, a US$30-million international project called ANDRILL pulled up the final piece of a core from beneath the Ross ice shelf. Previous coring efforts have offered peeks into Antarctica’s deep history — back as far as 34 million years when the …

Preliminary Results Of A Fecal Microbe Survey In An Eutrophic Lake, Wilgreen Lake, Madison County, Kentucky, Walter S. Borowski, Michael S. Albright

EKU Faculty and Staff Scholarship

Wilgreen Lake is a small (~14 mi²) eutrophic lake formed by damming several tributary streams to Silver Creek, Madison County, Kentucky. The lake receives runoff from industrial and urban areas (Richmond) that comprise ~10% of the total watershed area; most runoff is from cattle pasture or human developments encircling the lake. Present and past developments are on septic systems, and effluent from these systems is known qualitatively to seep into lake waters.

Our research group is currently conducting a study of the lake in order to identify major nutrient sources, and one possible tracer method is to quantitatively …

Residence Times And Temporal Variations Of 210Po In Aerosols And Precipitation From Southeastern Michigan, United States, Daphne Mcneary, Mark Baskaran

Environmental Science and Geology Faculty Research Publications

Daughter products of ²²²Rn (such as ²¹⁰Pb, half-life = 22.1 years, and ²¹⁰Po, half-life = 138 days) have been widely used as tracers to determine the removal rates of aerosols as well to obtain analog information on the behavior of other chemical species in the lower atmosphere. To establish the first data set on the depositional fluxes of ²¹⁰Po in bulk precipitation and concentrations in air samples from the midwestern United States, we measured the depositional fluxes of ²¹⁰Pb and ²¹⁰Po in the bulk (wet plus dry) and dry fallout by deploying a rain …

Stratification Of Southern Georgia Streams For Rapid Bioassessment Focusing On Differences In Structure And Function Of Black Water And Clear Water Streams, Salini Pradeep Pillai

Theses and Dissertations

As part of a rapid bioassessment project for the state of Georgia, relatively unimpaired reference streams and impaired sites were sampled for biological, chemical and physical parameters, and macroinvertebrates were identified. The metrics, biological, physical and chemical metrics, were selected using Ecological Data Application System Version 3.3.2k (EDAS). Discrimination efficiency and correlations were performed to determine the best metrics that separated impaired streams from reference streams and later on to form the index of stream water quality. Principal components analysis of the selected metrics showed that some of the blackwater reference streams and clearwater reference streams are randomly placed over …

Environmental Magnetic Records Of Mid-Late Pleistocene Drift Sedimentary Sequences From The Antarctic Peninsula, Pacific Margin, A. Venuti, F. Florindo, A. Caburlotto

ANDRILL Related Publications of Affiliates

The Pacific Continental Margin of the Antarctic Peninsula was the area of interest of the Sediment Drift of The Antarctic Offshore Project (SEDANO Project). A paleomagnetic and environmental study was carried out on four Pleistocene sequences from Drift 7. High resolution measurements were performed on u-channels and about forty-three discrete samples. This work focus on the definition of the mineralogy of the main magnetic carriers which is still matter of debate and on the study of the short time variability of magnetite grain-size which results particularly evident during the last glaciation. ARM/κ magnetic parameter resulted to be a good record …

A Pleistocene Warming Event At 1 Ma In Prydz Bay, East Antarctica: Evidence From Odp Site 1165, G. Villa, C. Lupi, F. Florindo, Stephan Pekar

ANDRILL Related Publications of Affiliates

Magneto-stratigraphic and nannofossil assemblage data from ODP Site 1165 evidence an anomalous warming event of the surface waters in and around Prydz Bay during the Early Pleistocene. This results from an increase in the abundance of nannofossils at Site 1165, that occurred at 1 Ma. High-resolution sampling permits a new bio-magnetostratigraphic interpretation for ODP Site 1165. A decrease in δ¹⁸O values at Sites 1165 and 1167 also occurs at this time, supporting the presence of warming conditions in the Prydz Bay area. A return to colder surface waters, indicated by the absence or rare occurrence of nannofossils in …

100 Million Years Of Antarctic Climate Evolution: Evidence From Fossil Plants, J. E. Francis, A. Ashworth, D. J. Cantrill, J. A. Crame, J. Howe, R. Stephens, A.-M. Tosolini, V. Thorn

ANDRILL Related Publications of Affiliates

The evolution of Antarctic climate from a Cretaceous greenhouse into the Neogene icehouse is captured within a rich record of fossil leaves, wood, pollen, and flowers from the Antarctic Peninsula and the Transantarctic Mountains. About 85 million years ago, during the mid-Late Cretaceous, flowering plants thrived in subtropical climates in Antarctica. Analysis of their leaves and flowers, many of which were ancestors of plants that live in the tropics today, indicates that summer temperatures averaged 20°C during this global thermal maximum. After the Paleocene (~60 Ma) warmth-loving plants gradually lost their place in the vegetation and were replaced by floras …

Herbivory In Antarctic Fossil Forests: Evolutionary And Palaeoclimatic Significance, C. M. Mcdonald, J. E. Francis, S. G.A. Compton, A. Haywood, A. C. Ashworth, Luis Felipe Hinojosa, J. Smellie

ANDRILL Related Publications of Affiliates

Many collections of Eocene Fossil leaves from Antarctica contain a rich store of insect trace fossils, indicating that insects were an important component of the unique forests that grew in polar regions. However, insect body fossils themselves are rare and so insect traces provide an excellent opportunity to examine both the palaeoentomology and the palaeoclimate of Antarctica. The fossils studied include Eocene leaves from both Seymour Island and King George Island on the Antarctic Peninsula. A database of all insect traces on the Antarctic fossil leaves was compiled and analysed in terms of the diversity of palaeoherbivory. The fossil leaves …

Terminal Cretaceous Climate Change And Biotic Response In Antarctica, V. C. Thorn, J. E. Francis, J. B. Riding, R. W. Raiswell, D. Pirrie, A. Haywood, J. A. Crame, J. M. Marshall

ANDRILL Related Publications of Affiliates

Latest Cretaceous to early Palaeogene climates in Antarctica are being investigated from an exceptional sedimentary sequence on Seymour Island (James Ross Basin, Antarctic Peninsula) to determine the nature of climate change at the end of the Cretaceous. It has been suggested that, following peak mid Cretaceous warmth, cooling during the Maastrichtian (~71-65 Ma) may have been severe enough for short-term glaciations at high latitudes, challenging the current view of an ice-free, Cretaceous greenhouse world. High resolution records of palaeontological, sedimentological, and geochemical signals are being obtained to investigate the climate and environmental context at the Antarctic margin prior to the …

Divergent Flow Of The West Antarctic Ice Sheet On The Outer Continental Shelf Of The Amundsen Sea During The Late Quaternary, T. J. Deen, R. D. Larter, K. Gohl, A. G.C. Graham, C.-D. Hillenbrand, G. Kuhn, J. A. Smith

ANDRILL Related Publications of Affiliates

Understanding the past glacial history of regions undergoing potential rapid deglaciation is essential in order to estimate the possible threat of sea level rise. Recently acquired data have given new images of mega-scale glacial lineations on the sea floor of the Amundsen Sea, which provide us a new understanding of the direction of glacial flow on the continental shelf of the Amundsen Sea region. Two adjacent areas of seafloor on the outer shelf of the Amundsen Sea embayment exhibit remarkably different styles of glacial lineations, and allow the interpretation of a divergent glacial trough for the Pine Island Glacier during …
